Hello. You can't carry out A/B extraction for free base. It is possible to do only with amphetamine salts. You can read manual from main page of Amphetamines section Amphetamine purification by acid-base extraction


Yes, you have to make solution like a sulfuric acid with acetone.


To cound how much acid do you need we will take 10 ml of amph free base as in example. 10ml of amph base / 0.936 g/ml = 10.6838 g. You have to count amount of moles: 10.6838g /135.21 g/mole = 0.079 moles of amphetamine. To produce monoamphetamine phosphate you have to take same amount of acid as amphetamine.
Hence: 0.079 moles * 97.994 g/mole = 7.743g of pure H3PO4. In case you have 70% acid solution, you have to take (7.743g * 100) / 70 = 11.06 ml of 70% H3PO4.
G.Pattonthanks for the explanations, they are very clear as usual!

and for the quantity of acetone to add do I have to calculate it too?

Can't edit my post but if 7.743g of pure H3PO4 is needed for 10ml of freebase amph, with a 85% solution we take (7.743*100)/85 = 9.109g of 85% H3PO4.
Density of phosphoric acid is 1.6845 g/cm3 then 5.40ml is needed ?
Or i'm totally out ?

Thanks for answer

keep in mind in the procedure solvent is evaporated to leave only freebase that in turn gets dilluted with acetone, if you just extract with non polar without evaporating dilluting might not be the best idea.

9.109g / 1,6845 g/cm3 = 5.40ml of 85% H3PO4 You are right! (y) Take into account that density of acid solution depends on concentration.
G.PattonThanks for clarification Sir!
About acetone how much i need to add ? Some calcul to do or a ladder to respect ?

Then if i resume,
I have to mix phosphoric acid with a ratio 1:10 to acetone, and i don't search to reach Ph 6 but i add the entire mixture and stir for get phosphate amphetamine ?

Thanks everyone for answer

Hello. We would like to get feedback from you about this supplier. Please, share us result of your deal.
G.PattonHi! I have just bought Sulphuric Acid and Nitric Acid from Aurelio. In the beginning they ask for proof of commercial activity, and I sent him a pdf indicating I am an independent researcher. And that´s all. I paid via Paypal and next day my order was delivered with tracking number. It arrived in 6 days.

user123qweWhat was the quantity ordered? I'd assume this technique works fine for smaller quantities but not that well for bulk?

KokosDreamsIt was 1 liter each. The minimum possible. But it looks like you can order 20l with no problem.

user123qweWould you mind sending me an example of such an PDF via DM? Doesn't needs to be the exact PDF you have sent but an example would be super useful

is the free base of amphetamin the same as the ampethaminoil ( a-oil ) what i can buy online in the internet? and does it mean that i can make the same steps like in the video (Synthesis from P2NP via Al/Hg)
with the (a-oil) if i join at minute 7:24?

What is sold online is basically amphetamine, which is illegal and diluted with solvents. The amount of freebase amine is equal to amount of amph salt you have. you can make sulfate, hydrochloride or phosphate salt and you ll see how little you actually made
